Running on Qualcomm Atheros QCA9558 (Scorpion) WiSoC platform, this range extender has 3 antennas (2 dBi) for 2.4Ghz network and another 3 antennas (3 dBi) for 5Ghz network. It supports MIMO 3x3:3 wireless with speed of up to 450 Mbps on 2.4GHz band and 1,300 Mbps on 5GHz band, totaling to 1,750 Mbps.

It has the same CPU with famous routers including Asus AC55U, TP-Link Archer C7, D-Link DIR-863, etc.

It is able to smartly allocate 1 antenna to communicate with upstream WiFi router, either using 2.4Ghz or 5Ghz network, while the other antennas serving the connected WiFi device. In this way, the effective bandwidth will not be halved as happened in the case of most WiFi range extenders.

It also supports "high speed mode" to use 1 band to send data and another to receive data concurrently, to optimize the overall WiFi speed and performance.

Its size is larger than my perception. The actual size is slightly larger than an adult's palm.

It comes with a Gigabit Ethernet port which can connect to a wired device or a network switch using network cable.

It has the modern TP-Link web user interface, and setting up is pretty easy. However, being easy to set up also comes with a trade off that there is not much advanced configuration for you to play around in the web user interface.

It allows you to control 3 ranges of WiFi signal power. You can also schedule to turn off its LED lights during certain period of the day.

Its maximum power consumption is only at 9W, which is about the same as an energy saving LED light bulb. You can schedule for it to automatically switch off at a particular time, and switch back on again at another time. This can save electricity during the time period when it is not likely to be used, such as during midnight.

This TP-Link RE450 range extender can be controlled and monitored from smartphone by using the TP-Link Tether app.

This WiFi range extender works pretty impressive, particularly in extending the reach and connection speed of 5Ghz WiFi network. I am quite impressed with its performance.
